I don't know if you remember, but over a year ago we had a discussion on this board about Pi aligning four Seas Excel 7" drivers for use as midbass units in my car. We also discussed using it as a small subwoofer enclosure in someone's porsche I believe. I completely forgot we ever had this discussion until thylantyr reminded me.
Anyway, I thought I would treat you to the results, thirteen months later.

The LED light ring is a pure special effect..

While I had long lost your original pi alignment for these drivers... I returned to my box designed software just a couple short months ago and did a custom box design myself, with trial and error until I got the best curve. The final result was a 0.66 cuft box per side (0.33 cuft per driver), with a box tuning of 48 Hz, with a single 3" diameter port. Those results virtually identical to what your program spit out a year earlier, other than the small deviation in box tuning.
The boxes sound fantastic... Midbass output is first rate. The best midbass performance I've heard out of any driver, period. The car sounds incredible, I wish you could hear it. MORE than worth the $1,100 dollars for the drivers and materials, and 12+ month wait... I've been running them for over a month, but I didn't think to hit ya up until now.
